FOOT-WARM ER.

SPECIFICATION forming part of Letters Patent No. 463,094, dated November10, 1891.

Application filed February 18, 1891, Serial No. 381,868. (No model.)

To all whom it may concern/.-

Be it known that we, WVILLIAM M. CARR, EDWARD B. HAHN, and JOSEPH B.JAoKsoN, citizens of the United States, residing at Tyrone, in thecounty of Anderson and State of Kentucky, have invented certain new anduseful Improvements in Footanners; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention consists in a'new and improved foot-warmer which 'iscomparatively simple and inexpensive in its construction and is veryeffective and satisfactory in its operation, and our invention will behereinafter fully described and claimed.

Referring to the accompanying drawings, Figure l is a perspective Viewofour invention with a part of the outer case or box broken away. Fig. 2is a transverse central sectional view of the same. Fig. 3 is a rearelevation with the rear wall of the casing broken away. Fig. 4illustrates in detail one end of the horizontal heating-cylinder withits removable flanged cap.

The same numerals of reference indicate corresponding parts in all thefigures.

Referring to the several parts by their designating-numerals, 1indicates an air-tight sheet-metal box or air-chamber of any suitable ordesired size. The rear side of this box is much high er than its frontside, and the top 2 of the box inclines down from the rear to the frontside thereof, forming a convenient foot-rest, upon which the feet of theuser are placed. At the lower end of the inclined footrest 2 is arrangeda longitudinal raised heelbar 3. 1

At the bottom of the foot-warmer is arranged a large fluid-reservoir 4-,which practically forms the lamp-body. At the center or near one end, ifpreferred, of the rear part of this body or reservoir is arranged aburner 5, and a tin or sheet-metal chimney 6 surrounds this burner andleads up to the heat ing-cylinder 7.

Within the upper part of the box 1, about one inch below the top, isarranged the longitudinal heating-cylinder 7, the ends of which extendthrough the ends of the box 1 for a distance of about one inch and haveformed in their outer ends a series of perforations 8. The outerperforated ends '7 of the heatingcylinder 7 are closed by the removablecaps 0. These caps are formed each with an inner flange 9 of suchdiameter that it will fit snugly within the outer end of the heatingpipe8, and around the outer edge of the cap is formed a wider flange 10,which, when the cap is placed in position on the end of the pipe, willextend around the series of perfora tions 8, but will not be in contactwith the outer surface of the pipe end.

The chamber 1 is formed with an inclined bottom 11, extending from theburner to the forward end thereof, thus forming a draftchamber, the ends11 of which are formed with perforations 12, and the lower end. of theperforated burner-casing 13 extends into and communicates with the rearend of this chamber. This construction furnishes the necessary supply ofair for the lamp-flame, as will be readily understood. It will now beseen that the heat of the lamp-flame, together with the smoke and otherproducts of combustion, will pass up through the lamp-chimney 6 into theheating-cylinder 7. The hot air will pass along through the cylinder toeach end thereof and make its escape through the perforations 8 of theouter ends 7 of the cylinder 7. The current thus produced will draw theouter air through the perforations 12 to the burner, thus greatlyassisting the draft and combustion.

By forming the double flanged end caps 9, as set forth, when the lamp isfirst started, the caps can be removed to assist the draft until thecirculation of air is well established, and when a good draft has beensecured the caps 9 are replaced, when the hotair, &c.,will pass outthrough the perforations 8, as before described. The wide outer fiangesl0 prevent the air from blowing directly into the perforations 8 andthus interfering with the draft and the escape of hot air outwardthrough the said perforations. A damper 14: is arranged at the pointshown to regulate the supply of air to the burner and thus control thedraft.

The body of the heating-cylinder 8 may be either straight, as shown, orformed in a coil, if preferred.

If desired, the ends of the cylinder 8 may be connected by return-tubes15 1.5 with the burner, as shown in Fig. 3, which will have the effectof increasing the draft and preventing the possible escape of smoke intothe apartment. It is obvious that one or more burners may be employed,according to the size of the foot-warmerand the amount of heat required.It is alsoobvious that the reservoir 4 maybe dispensed with and anordinary lamp be employed in its place. Small openings 16 16, in whichmica is set, are formed opposite each other in the back of the box 1 andthe rear of the lamp-chimney, through which the flame of the lamp can beobserved to see that it is turned to the desired height.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

l. The combination of a metal box, the heating-cylinder 7, having theopen ends, which extend through the walls of the box and which areformed at a certain distance from their open extremities with theannular series of perforations 7*, a lamp having a chimney communicatingat its upper end with the heatingcylinder, and the removable end caps 9,formed with the narrow inner flanges 9, which hold them in position,andthe wide outer protecting flanges 10, which extend over and outside of,but not in contact with, the apertured ends of said heating-cylinder,substantially asset forth.

2. The combination of the metal box 1, formed with the inclined top 2,constituting a foot-rest, and the inclined bottom 11, and having the endperforations 12, the lamp-reservoir 4, the burner 5, a heating-cylinderarranged horizontally in the upper part of the box 1 and having its openends extending through the Walls of said box, and the chimney connectingthe burner with the heatingcylinder, substantially as set forth.

3. The combination of the metal box 1, formed with the inclined top 2,constituting a foot-rest, and the inclined bottom 11, and having the endperforations 12, the fluid-reservoir 4:, the burner 5, theheating-cylinder 7, formed with the perforated ends 7, which projectthrough the walls of the box 1, the removable end caps 9, formed withthe inner flanges 9 and the Wide outer flanges 10, the chimneyconnecting the burner with theheating-cylinder, and the return-tubes 15,arranged as specified, substantially as set forth.

In testimony whereof-we affix oursignatures in presence of twowitnesses.
